NOTE:
When trying to remove an accessory, if the quick-
change collet begins to unthread from the tool, repeat the
install process.
DANGER:
If you are changing an accessory immediately after use,
be careful not to touch the collet or the accessory with
your hands or fingers. You will get burned because of
the heat build-up from operation. Always use the wrench
provided or allow the collet to cool.
USING MANDRELS
See Figure 5, page 15.
The most common types of mandrel to use with this tool
include the standard mandrel which is used with cut-off
discs, grinding wheels, emery wheels, and cut-off wheels.
Screw mandrels are used with polishing wheels and polishing
drums. Drum mandrels are used with sanding drums.
To install:
Remove the battery pack.
Install the mandrel.
If using the standard mandrel:
Depress and hold the spindle lock button and rotate the
mandrel by hand until the spindle lock engages preventing
further rotation.
Insert the slot end of the provided wrench into the slot
on top of the mandrel and unscrew.
Remove mandrel screw and washer.
Place desired accessory over mandrel shaft and align
accessory hole with mandrel hole.
Insert mandrel screw with washer through the accessory
and mandrel shaft holes.
NOTE:
The mandrel washer should be placed between
the mandrel screw and the accessory.
Tighten using provided wrench.
If using the screw mandrel:
Align desired accessory hole with mandrel screw head.
Screw accessory onto mandrel by twisting clockwise until
secure.
If using the drum mandrel:
Align appropriate sized sanding drum over mandrel and
push down to completely cover drum end of mandrel.
NOTE:
If necessary, tighten the screw on the drum
mandrel head to expand the drum and securely hold the
sanding drum in place.
BALANCING ACCESSORIES
For precision work, it is important that all accessories be properly
balanced. To balance an accessory, slightly loosen the quick-
change collet and give the accessory or collet a 1/4 in. turn.
You should be able to tell by the sound and feel if the accessory
is running in balance. Continue adjusting in this fashion until
the best balance is achieved. Replace accessories if they
become damaged or unbalanced.
TURNING THE ROTARY TOOL ON/OFF
See Figure 6, page 15.
To turn the tool
ON
: move the ON/OFF switch to the ON
position.
To turn the tool
OFF
: move the ON/OFF switch to the
OFF position.
SELECTING THE RIGHT SPEED
See Figure 6, page 15.
To increase the tool’s speed, rotate the speed control
dial clockwise. To decrease the speed, rotate the dial
counterclockwise. To control the speed with a foot pedal
(not included), rotate the dial completely counterclockwise.
The rotary tool has a speed range of 1,000-25,000 RPM. To
select the right speed for each job, use a practice piece of
material. Vary speed to find the best speed for the accessory
you are using and the job to be done.
Use the speed control dial to set the best speed for the job.
When the dial is set to the maximum setting, approximately
25,000 RPM is achieved.
Refer to the
Application Speed Recommendations
table
to determine the proper speed based on the material being
worked and the type of accessory being used.
SLOWER SPEEDS
Certain materials, some plastics for example, require a
relatively slow speed because the friction of the tool generates
heat and causes the plastic to melt at high speed.
Slow speeds (15,000 RPM or less) are usually best for
polishing operations using the polishing accessories. They
may also be best for working on delicate projects, delicate
wood carving, and fragile model parts.
Higher speeds are better for carving, cutting, and shaping
wood.
Hardwoods, metals, and glass require high speed operation.
Drilling should also be done at high speeds.
To determine the optimum operational speed for different
materials and accessories, refer to the
Application Speed
Recommendations
table. Look this table over and become
familiar with it.
The best way to determine the correct speed for work on
any material is to practice for a few minutes on a piece of
scrap, even after referring to the table. You can quickly
learn that a slower or faster speed is more effective just by
observing what happens when you make a pass or two at
different speeds.
When working with a scrap piece of plastic, start at a slow
